HEATING-DRUM.

SPECIFICATION forming part of Letters Patent No. 459,413, dated September 15, 1891.

Application tiled February 10, 1891 Serial No. 380,943. (No model.)

To aZZ whom, it may concern.:

Be it known that l, ROBERT PGH, a citizen of the United States, residing at Casselton, in the county of Cass, State of North Dakota, have invented certain new and useful Improvements in HeatingDrums, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvementsin heating-drums; and it has for its objects, among others, to provide an improved device of this character Whereby a complete ventilation of the room is obtained, a large amount of heating-surface is provided, and a portable device secured, which can be readily applied in position without the employment of skilled labor. I have a cylinder with nipple or other provision for connection with the smoke-pipe, a foul-air pipe passing through the cylinder and emptying directly into the smoke-flue or chimney, and a triangular chamber within the cylinder, and preferably removable to aid in the cleaning thereof when desired, the parts being so arranged that the products of combustion must necessarily pass the whole length of the interior chamber upon two sides thereof, so as to eifcctually heat the air therein. The foul-air pipe is constructed in the form of a truncated cone, so that the air will be drawn or sucked up and the room most effectually ventilated.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, With the letters of reference marked thereon, form a part of this specification, and in which- Figure l is a vertical section through a drum embodying my improvements. Fig. 2 is a cross-section through the same on the line a: of Fig. l.

Like letters of reference indicate like parts in both views.

Referring now to the details of the drawings by letter, A designates the cylinder, which may be of any required size and material. It is provided with a removable cap or top B, havinga surrounding flange a, which embraces the Lipper end of the cylinder, as seen in Fig. l, the said cylinder being provided with a bead or analogous provision b to limit the movement of the cover or cap.

The cylinder may be provided with legs` or supports c, as indicated in Fig. 1, and is also provided with a nipple or neck d for connec- E is the heating-chamber Within the cylinder. It is preferably made removable to aid in cleaning the device when necessary, and for this purpose it is provided with flanges e, as seen in Fig. 2, which are designed to slide in the guides f, secured to the inner wall of the cylinder, as seen in both views. This "chamber is substantially triangular in crosssection, as seen in Fig. 2, and is provided suhstantially centrally at each end with a neck or nipple f t0 connect with the inlet and outlet pipes, as seen in Fig. l. The necks or nipples are so arranged relatively to the ends of the chamber that when the latter is in place Within the cylinder a space will be left between the said ends and the top and bottom of the cylinder, as seen in Fig. l, so as to provide for the circulation of the heat all around the interior chamber. The metal of the chamber does not extend below the bottom of the chamber, and thus the passage-way g is provided beneath the said bottom for the products of combustion into the passage-Way F, as seen in Fig. 1. The metal above the top of the chamber is extended to form a shield or partition h, and the upper end is extended horizontally and lies in close contact with the under face of the cover or cap, as seen in Fig. 1, so that the communication above the top of the chamber is completely closed, and

thus the products of combustion are forced to IOO travel downward and beneath the bottom of tre clhamher, as illustrated by the arrows in 'lhe side of the chamber and the partition h form the passage-Way F, which at its upper end communicates with the smoke-flue G, and extended centrally within this passage-way F is the foul-air pipe H, which is tapered with its larger end at the bottom, and said larger end extends through the bottom of the cylinder and is provided with openings z', through which the foul air in the room finds its Way, as indicated by the arrow. The smaller end of the foul-air pipe extends above the top of the cylinder into the smoke-flue, as seen in Fig. l. A Suction is created by the outfiowing products of combustion and the t'oul air is eiectually withdrawn from the room.

The device is simple, cheap, durable, andin practice has proved most efficient for the purposes for which it is intended.

l. Thecylinderhavinginlet-pipeextending within the same, combined with a heatingchamber within the cylinder and having ingress and egress openings and dividing the cylinder, and a foul-air pipe extended through the smaller compartment thus formed, as set forth.

2. The cylinder having smoke-pipe extended within the same, combined with the chamber Within the cylinder and having ingress and egress openings with a space between the bottom of the chamber and cylinder, and a partition between the top of the chamber and the top of the cylinder, substantially as specitied.

3. The combination, with the cylinder and its inlet smoke-pipe, of the triangular heating-chamber within the cylinder and having a portion extended above its top to shut off communication between the main portion of the cvlin der and its exit-flue, substantially as specified.

4. The combination, with the cylinder and its smoke-pipe and triangular' heating-chamber dividing the cylinder into two compartments, of the tapered foul-air pipe extended through the smaller compartment, substan tially as specified.

5. The combination, with the cylinder provided with vertical guides, of the triangular heating-chamber provided with side flanges engaging said guides and having a portion extended above the top of the chamber, substantially as and for the purpose specified.

6. The combination, with the cylinder provided with vertical guides, of the triangular heating-chamber provided with side flanges working in said guides and having the metal extended above the top of the chamber and its upper end turned horizontally, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
